Let`1 ; ` 2 ; : : : ; ` d be disjoint parallel lines in the plane. A d-interval is a subset of their union that intersects eachì in a closed interval. Kaiser Discr. Comput. Geom. 18(1997) 195{203] showed that any system of d-intervals containing no subsystem of k + 1 pairwise disjoint d-intervals can be pierced by at most (d 2 ? d)k points. We show that this bound is close to being optimal, by ...

in this paper smart operation of micro energy hub is presented. energy hub system consists of certain energy hubs and interconnectors that are coordinated by energy hub system operator. an energy hub contains several converters and storages to serve demanded services in most efficient manner from available energy carriers. in this paper, the flexibility of energy delivery point is enhanced u...

Abstract. After formulating the design problem for Resampling Kernels used in Magnetic Resonance Spiral Image Reconstruction, we show that an iterative Gauss-Seidel-type interior-point optimization method is suitable (fast and light-weight) for embedded uses. In contrast to previous practice, we directly optimize a computationally efficient, piecewise-linear kernel rather than an analytic funct...

The optimal window, the time limited sequence whose energy is most concentrated in a nite frequency interval is related to a particular discrete prolate spheroidal sequence. The optimal window is actually a family of windows with many degrees of freedom. The Kaiser window is an approximation to this optimal window. Kaiser used this approximation because the standard method employed to compute t...

this paper demonstrates a method to how reserve capacity and cost allocation could be determined in a pool-based and disaggregated market model. the method considers both the spinning reserve and interruptible loads as the operating reserve services. in the proposed market, generators and consumers (including participation of interruptible loads) submit offers and bids to the independent system...
